RADIATOR. i;

Specification of Letters Patent.

Patented Feb, 6, 1917.

Original application filed July 12, 1911, Serial No. 638,057. Dividedand this application filed November 25,

To all whom it may concern:

Be it known that I, KINDERMAN M. BOB- LETT, a citizen of the UnitedStates, residing at Toledo, in the county of Lucas and State l of Ohio,have invented certain new and useful Improvements in Radiators, of whichthe following is a specification.

My invention relates to fluid cooling apparatus and particularly tocondensers or 1G radiators.

' tion and unlikely to get out of repair.

A further object is to provide a radiator comprising a plurality ofunits, each unit formed of two members, such units being capable ofbeing assembled into cores of different sizes and proportions. Theresulting unit permits the use of a radiating fin of any desiredconstruction. Such radiating fin however, forms no part of the presentinvention.

E 85 With the above primary and other incidental objects in view as willmore fully appear in the specification, the invention consists of thefeatures of construction, the parts and combinations thereof and themode of operation or their equivalents as hereinafter described and setforth in the claims.

In the drawings, Figure 1 is a front elevation of the assembledradiator. Figs. 2 and a5 3 are opposite detail perspective views of twounit side members ready to be engaged one with the other. Fig. 4 is aperspective view of the assembled unit with a radiating fin plate ofordinary construction inserted within the unit between the side members.Fig. 5 is a plan view of the blank for the side member and Fig. 6 is adetail perspective view of a radiator fin plate which may be employedwith the unit forming the subject matter hereof. Fig. 'Zis a detailperspective Serial No. 733,384.

view of a plurality of the radiator units assembled into a core. Figs. 8and 9 are sectional plan views of modifications.

Like parts are indicated by similar characters of reference throughoutthe several Views.

The radiator of which the particular radiator unit forming the subjectmatter hereof constitutes a part comprises a frame having in the upperportion thereof a receiving .chamber 1 and in the lower portion adispensing chamber 2 connected with the receiving chamber by a pluralityof conduits through which the water passes from the receiving to thedispensing chamber. These conduits may be either continuous from onechamber to the other, or they may be of short length, and arranged intiers, separated by intervening water spaces or auxiliary chamberscommon to all the conduits in a manner common and well-known in radiatorconstruction. The conduits connecting the chambers are formed byarranging a plurality of similar radiator units side by side butseparated one from the other to form intermediate water spaces orconduits which communicate with the respective chambers.

The units are each formed from two similar side members 3 such as areshown in Figs. 2 and'3 united, one to the other, in opposite relation asindicated in Figs. 2 and 3 and Fig. 4. The side member 3 is formed froma single sheet metal blank cut and folded on lines as indicated in Fig.5. The

portion 4. The extension of the blank at one end of said wall portion 4is bent to a position perpendicular to the wall 4 upon line aa to form aright angle flange 5. The extension of the wall portion 4 at theopposite end of the blank is bent upon the line bb to a positionperpendicular to the wall portion 4 to form a second end flange 6 whichflange 6 is again bent upon line 0-0 and dd throughout successivereverse bends, the several portions of the flange being reduced toparallelism as shown at 7. The side extension of the blank projectinglaterally from the wall portion 4 is bent upon line ee to a positionperpendicular to the plane of the wall portion 4 and is 119? again benton line ff throughouta right -fin-plates If so desired such radiator finangle whereby the extremity of the lateral extension will extendparallel with the wall portion 4 but spaced away therefrom. The sideextension thus forms a marginal inturned side flange or channel 8. Theopposing member 3 is similarly formed and comprises the wall 4 andflange 56 and 8. The flange 6 is reversed at 7 as before mentioned.

The several radiator units are formed by uniting two of such sidemembers one with the other in reverse relation whereby the terminalflanges 5 of each member will engage within the overlapping scams 7formed upon the terminal flanges 6 of the opposite members. There isthus formed a box like unit having opposite parallel side walls 44connected at their extremities by the right angle flanges 5 and 6.Eachof the side walls 44 has a longitudinal marginal flange 8- locatedin diagonally opposite relation upon the unit. That is, the longitudinalmarginal flange 8 upon oneside of the unit will be at the right sidewhile the corresponding marginal flange upon the opposite side of theunit will be at the left side.

In assembling the radiator core the several units are arranged side byside as shown in Fig. 7 with the flanged edge of one unit engaging theplane edge of the next succeeding unit. Inasmuch as each unit engagesthe succeeding unit at one side and the preceding unit at the oppositeside there is formed intermediate the successive units longitudinallydisposed water conduits 9 adapted to be placed in communication with thereceiving and dispension chambers l and 2.

It is to be particularly noted that the side walls 4 of each radiatorunit do not form the opposite side walls of a single conduit but thateach side wall 4 of each unit forms a side wall of succeeding orseparate conduits, the opposite walls of such succeeding conduits beingformecf by the side members 4 of the preceding and succeeding radiatorunits.

It is to be'further noted that the side members 3 forming the severalunits are connected one to the other at the extremities corresponding tothe terminals of the water conduits 9 while the unit thus formed by theterminal connection of the side members is connected to succeeding andpreceding units by their lateral flanges extending in longitudinalrelation with the intermediate conduits 9. The units thus formed do notcontain in themselves a water conduit or water space but inclose an airspace formed by the side walls 4 of separate succeeding conduitsconnected at their terminal extremities by the interlocking flanges 5and 6.

The radiator thus constructed may be employed with or without additionalradiator plates of any desiredconstruction may be inserted within theair space of the unit formed intermediate the side walls 4.4.

Such fin plates form no part of the present nvention.

There have, however, been shown in the drawings two forms of fin plates,one of which asillustrated in Fig. 4 comprises a single plate foldedupon itself throughout a series of right angle and reverse bends to forma central septum from which project in opposite directions a pluralityof plaits arranged at right angles to septum. In Fig. 6 is shown asecond form of radiator fin plates, comprising a plate of meandrousformation and adapted to be inserted within the air space between theside walls 44. After the side members and the units formed therefrom areassembled as before described they are united into one structure bydipping or soldering whereby the terminal flanges 5 and 6 of successiveside members are united and the succeeding units are united by theirside flanges.

In Fig. 8 is shown. a sectional plan view of a modification in which theextremity of the lateral side flange 8 is bent outward and thence inwardupon itself to form a re: cess or groove '10 inwhich the edge of theadjacent side wall 4 engages.

In Fig. 9 is shown a similar construction in which the edge of the sidewall 4 is bent laterally to engage the recess lO upon the flange of theadjacent side wall.

From the above description it will be apparent that there is thusproduced a device of the character described possessing the particularfeatures of advantage before enumerated as desirable but whichobviouslyis susceptible of modification in its form, proportion, detailconstruction and arrangement of parts without departing from theprinciple involved or sacrificing any of its advantages.

While in order to comply with the statute, the invention has been hereindescribed in language more or less specific as to certain structuralfeatures, it is to be understood that the invention is not limited toany specific details but that the means and mechanism herein shown anddescribed comprise but one mode of putting the invention into effect andthe invention is therefore claimed broadly in any of its possible formsor modifications within the scope of the appended claims.

The'subject matter hereof was originally disclosed in application SerialNo. 638,057,

upon which was issued Patent No. 1,053,269, i

of which this is a division.

Having thus described my invention, I claim:

1. In a radiator, a plurality of independent plates arranged in spacedrelation, a

flange projecting laterally from the terminal edge of each plate and aflange projecting laterally from the longitudinal edge of each plate,said flanges being extended in opposite directions from the plane of theplate and connected with the adjacent plates at opposite sides thereof.-

2. In a radiator, a plurality of substantially parallel spaced plateshaving both transverse and longitudinal flanges the transverse andterminal flanges being extended in opposite directions from the plane ofthe plate and connecting the succeeding plates one with another.

A radiator member comprising a plate the terminal edge of which is bentlaterally in one direction from the plane of the plate and thelongitudinal edge of Which is bent laterally in the opposite directionfrom the plane oi the plate, a plurality of said plates being adapted tobe arranged in spaced relation and connected one to another by saidlaterally bent edges.

4-. A. radiator comprising a series of independent side plates, amarginal flange upon one edge of each plate, a terminal flange upon theend of each plate turned in a direction opposite that of the saidmarginal flange, the terminal flange of each plate being connected withthe adjacent plate upon one side and the marginal flange being connectedwith the adjacent plate upon the opposite side.

A radiator core comprising a plurality of substantially flat independentparallel plates arranged side by side in spaced relation, andintermediate flanges connecting the plates one With the other, theflanges being alternately arranged at the sides and ends of the plateswhereby there Will be formed intermediate the plates alternatingvertical and transverse passages one for air and the other for Water.

In testimony whereof, I have hereunto set my hand this 11th day ofNovember, 1912.
